I would be for (1) errata or amendment as reality is that there is
probably no WSGI implementation that disallows an argument to
readline() given that certain Python code such as cgi.FieldStorage
wouldn't work otherwise.
For such a clarification on existing practice, I see no point in
having to change wsgi.version in environ as it would just cause
I would also like to see other changes to WSGI specification but now
is not the time, let us at least though get this obvious issue with
API dealt with. After that we can then perhaps have a discussion of
future of WSGI specification and whether there really is any interest
in future versions with more significant changes. Although, personally
I will not be holding my breath for that to happen. :-)
